JAR SEAL AND METHOD OF APPLYING THE SAME.

Application filed December 14, 1918. Serial No. 266,685.

T 0 all 'aihom it may concern Be it known that I, BERNARD F. RoEHRIc,.

a citizen of the United States, and a resident of the city of Pasadena,county of Los Angeles,.and State of California, have invented certainnew and useful Improvements in J arSeals and Methods of Applying theSame, of which the following a specification.

My 'nvention relates to improvements in jar seals and methods ofapplying the same,

and has for its object the provision of an improved construction andmethod of this character, whereby jars or other receptacles containingmaterlal which it is desired to protect from contact with theatmosphere, may be quickly and efiiciently sealed.

Otherobjects will appear hereinafter.

The invention consists in the j ai seal and method of applying the samehereinafter described and claimed.

The invention will be best understood by reference to the accompanyindrawings forming a part of this specifica ion, and in which, v

Fig. 1, is a sectional view illustrating an adhesive supplying pad asused,

Fig. 2, a top plan view of the moisture applying pad, as used, and

Fig. 3, a side view, illustratin a ar in position for effecting thefinal sea ing, thereof, and alsoi such a jar finally sealed and closed.

The construction illustrated comprises an ordinary jar 4, provided witha removable screw top 5, such as an ordinary glass or porcelain jar forcontaining cold cream or the like, which has enough consistency toprevent flow thereof. The seal consists of a disc 6 of gelatinousmaterial, such as ordinary gelatine paper, secured over the mouth of thejar and enclosed and protected by the removable cover cap 5, as shown.

The preferred method of applying the sealing disc 6 consists inproviding an adhesive supplying pad 7 of felt or similar porousmaterial, said pad being impregnated or saturated with an adhesive, suchas a mixture of glue and gelatine, when in aheated state. This pad isarranged in a tray 8, partially filled with water and positioned over aburner 9, whereby the same may be maintained in heated condition. Insuch condition the adhesive pad 7 will be constantly maintained in asoftened and moist condition, in which condition it readily and Iquickly serves its purpose. l also provide another pad 10, of felt,which is moistened with water, and on this pad are arranged a pluralityof the discs 6, as indicated in Fig. 2, said discs being thus moistenedby the water in pad 6 before their application to the jars. Another pad11, of dry felt, is also provided and arranged in immediate proximity tothe pads 7 and 10, when I am ready to proceed with the sealing -opera-,tions. To effect the sealing of a jar, the same is applied to the pad 7,as indicated in Fig. 1, being pressed slightly into said pad and turnedso as to apply the adhesive thoroughly to the edges of the mouth of thejar. Then the jar, still in inverted position, is applied at once to oneof the moistened discs 6, which will adhere to the edges of the mouth ofthe jar, whereupon the jar, still in inverted position, is at onceapplied to the pad 11 and slight downward pressure exerted on said jar,which causes perfect and continuous contact of the sealing disc with theedges of the jar and thus a perfect seal. A closure cap 5 is thenapplied to the jar, when the sealing and closure thereof is complete.

In this manner and by this means, a perfecthermetic seal may be providedfor jars or other receptacles, such as cosmetic receptacles, preserve orjelly jars o-r glasses, and the like. When it is desired to remove thecontents, the seal 6 may be broken with the finger or removed with aknife having little or no strength ofv its own. By means of the methodset forth, the sealing of jars containing nonflowing material may bereadily and quickly effected. While the material in the jar is of aflowing nature, the method outlined above cannot be employed, but it is.obvious that adhesive sealing discs may be readily applied to the jarsin upright posi tions. The moisture supplied to the sealing discs by thepad 10 before their application to the jars softens and permits slightstretching of the same in the application, and the drying thereof causesshrinkage which stretches the sealing discs tightly and smoothly overthe mouth of the jar and also serves as a test to determine whether ornot the adhesion is perfect and continuous.

While I have illustrated and described the preferred form of seal andmethod of applying the same. these are capable of variation andmodification without departing from the spirit of the invention. 1,

, of procedure set forth, but desire to avail myself of such variationsand modifications as come within the scope of the appended claims.

Having described my invention, whatv I claim as new and desire to secureby Letters Patent is 1. The method of sealing receptacles which consistsin providing an adhesive supplying pad; a water moistened pad and a drypad arranging one or more sealing members on said moistened pad; andapplying the edges of the mouth of said'receptacle to said adhesivesupplying pad, then to one of said sealing members and then to said drypad, substantially as described.

2. The method of sealing receptacles which. consists in providing anadhesive supplying pad of felt,- a water moistened pad of felt, and adry pad of felt; arranging one or more sealing members on said moistenedpad; and applying the edges of the mouth of said receptacle to saidadhesive supplying pad, then to one of said sealing members and then tosaid dry pad, substantially as described.

- ,3. The method of sealing receptacles which consists in providing anadhesive supplying heated pad; a water moistened pad and a dry pad;arranging one or more sealing members on said moistened pad; andapplying the edges of the mouth of said receptacle to said adhesivesupplying pad, t en to one of said sealing members and then to said drypad, substantially as described.

4. The method of sealing receptacles which consists-in providing anadhesive supplying heated pad of felt, a water moistenedpad of felt, anda dry pad of felt; arranging one or more sealing members on saidmoistened pad; and applying the edges of the mouth of said receptacle tosaid adhesive supplying pad, then to one of said sealing members andthen to said dry pad, substantially as described. v

5. The method. of sealing receptacles which consists in providing a padof felt saturated with adhesive material and immersed in a hot waterbath, a water moistened pad of felt and a dry pad of felt; arranging aplurality of sealing members on said moistened pad and applying theedges of the mouth of said receptacle to said adhesive supplying pad,then to one of said sealing members and then to said dry pad,substantially as described.

6. The method of sealing receptacles which consists in providing anadhesive supplying pad and a water moistened pad;

arranging one or more sealing members on said moistened pad and applyingthe edges ofthe mouth of said receptacle to said ad- -which consists inproviding a supplying padcontaining hot adhesive and a water molstenedpad; arranging one or more members on said moistened pad; applying theedges of the mouth of said receptacle to said adhesive supplyingpad',and then to one of said sealing members, substantially asdescribed.

8. The method of sealing receptacles which consists in applying ahotplasticadhesive substance of a congealable material to the edges, ofthe mouth thereof; and then applying a semi-fusible sealing membercontaining similar congealed material to said adhesive substance to forma bond therei adhesive containing a particular congealable substance tothe edges of the mouth thereof; and then applying a fusible sealingmember containin similar congealedsubstance to said adhesive substanceto form a bond therewith, substantially as described.

10. The method of sealing receptacles which consists in applying amixture of hot gelatine and adhesive to the edges of the mouth thereof;and then applying a sealing member coated with congealed gelatin to saidmixture to form a bond therewith, substantially as described.

11.-The method of sealing receptacles which consists in applying a hotmixture of adhesive substance containing congealable gelatin to theedges of the mouth thereof; and then applying a congealed gelatinesealing member which forms a bond with said adhesive substance,substantially as de-- stance fused therewith and forming a hermeticalclosure, substantially as described.

In testimony whereof I have signed my name to this specification inthepresence of two subscribing witnesses.
